TEST BENCHES FOR SHUT OFF VALVES DN 10…800 MM

PURPOSE:. testing the valve's body for strength and density;. gate tightness tests;. environmental leakage tests (including gland seals);. operation test;. pressure safety valves gate tightness test;. pressure safety valves operation tests.TESTED ITEMS:. gate valves;. ball valves;. stop valves (globe valves);. check valves;. butterfly gates;. plug valves.TESTED UNIT CONNECTION TYPE:. flanged (according ASME B 16.5, GOST 12815 etc.);. welded ends (according ASME B 16.25, GOST, etc.);. threaded-end;*. true union.*ADVANTAGES:-Clamping of tested valve provided by hydraulic cylinder, optionally test bench canbe equipped with proportional clamping control system, which excluding axialcompression applied to the valve body during clamping by hydraulic cylinder,during high pressure testing.*- The two-sided gate sealing during tests do not require the tested valverearrangement, which significantly reduces the test time.- The bench is equipped with the water-collection tray with stainless steel tank.*- The test preparation time is significantly reduced by using the high-pressure fastcoupling hoses.- The bench is quickly adjusted to face-to-face dimensions of valve by using theelectrically driven cross-head.-The patented design of the self-sealing adapters exclude axial compressionduring the tests, which ensures the test reliability, protects the valves againstdeformation, and extends the valve life.*- All water-wetted parts are corrosion-proof.- The bench can be equipped with replaceable sealing adapters.*- Increased-diameter hoses reduce the time of the valve filling with the test medium.-Turning upper cross-head is used to simplify the valve installation procedurebefore testing.- The test preparation time is significantly reduced by using the high-pressurequick-connect hoses.- Fast clamping and centering of the tested valve is ensured due to synchronizedtravel of the straps.- Test bench allows visual detection of seat leakage point.
